No
The document does not mention AI, ML, or any related concepts like image processing, training sets, or performance metrics typically associated with AI/ML devices. The description focuses on standard electrical stimulation functions.

Yes.
The device is used for therapeutic purposes such as relaxation of muscle spasms, prevention of disuse atrophy, muscle re-education, post-surgical stimulation, and maintaining or increasing range of motion. It is described as "adjunctive therapy for the treatment of medical diseases and conditions."

No
The device, a Powered Muscle Stimulator, is used to apply electrical current for therapeutic purposes like muscle relaxation, re-education, and preventing atrophy or venous thrombosis. Its stated functions are all related to treatment, not diagnosis.

No

The device description explicitly states "Powered Muscle Stimulator, HT-329M1, HT-329M2, HT-329M3, and HT-329M4", indicating a hardware device that applies electrical current.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Function: The description clearly states the device applies an electrical current to electrodes on the patient's skin to stimulate muscles. This is a direct interaction with the patient's body, not an analysis of a specimen taken from the body.
  • Intended Use: The intended uses are all related to muscle stimulation and rehabilitation, which are therapeutic applications, not diagnostic ones based on analyzing biological samples.

Therefore, this device falls under the category of a therapeutic medical device, specifically a powered muscle stimulator, rather than an In Vitro Diagnostic.

Trade/Device Name: Home Care various models of Powered Muscle Stimulator, HT-329M1, HT-329M2, HT-329M3, and HT-329M4 Regulation Number: 21 CFR 890.5850 Regulation Name: Powered muscle stimulator Regulatory Class: II Product Code: IPF Dated: July 26, 2003 Received: July 31, 2003

Dear Ms. Cheng:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments. or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
